Garantía sobre Fianzas is a bond-guarantee program operated by Nacional Financiera (NAFIN), Mexico's federal development bank, designed to expand the bonding capacity of micro, small, and medium enterprises (MIPYMEs) bidding for public and private contracts. The program backstops participating bonding companies — Aserta, Atlas, Chubb Monterrey, Fiducia, and Insurgentes — so that those companies can issue advance-payment bonds, performance bonds, and quality bonds on behalf of MIPYMEs that might not otherwise qualify. Both Mexican peso (MXN) and US dollar (USD) denominated bonds are covered.

Eligibility is open to MIPYMEs and individuals conducting business activity with annual sales of no more than MXN 250 million. Applicants must hold a signed contract to supply goods, services, or public works to a federal agency, state enterprise, state or local government body, or a private firm in industry, commerce, or services; the primary (agricultural and extractive) sector is excluded. NAFIN's guarantee coverage reaches up to MXN 30,000,000 per contract, with the term tied to the duration of the underlying contract.

To access the program, an eligible business presents its contract and financial documentation to one of the five participating bonding companies, which processes the fianza application under the NAFIN guarantee umbrella. Because the guarantee de-risks the bonding company rather than the contracting entity directly, the cost and time to obtain a performance or advance-payment bond is reduced significantly for qualifying MIPYMEs. This instrument is particularly relevant for small construction and services firms competing in public procurement tenders where bonds are a mandatory bid requirement.

NAFIN bond-guarantee program covering up to MXN 30,000,000 per contract, enabling Mexican MIPYMEs to obtain advance-payment, performance, and quality bonds for public procurement and private sector contracts.
